You use surface area whenever you want to know the area of a non-flat surface. This is useful in a lot of physical applications. For example, heat flow, electrical current flow, or fluid flow through an irregularly-shaped region all are defined in terms of integrals over the boundary, and integration is taken with respect to surface area.
Surface area is used to calculate the amount of material required to cover or coat an object, such as paint or wallpaper. It is also used in heat transfer calculations, such as determining the rate at which heat is exchanged between an object and its surroundings. Additionally, surface area is used in geometry to calculate the size and shape of 2D and 3D objects.
use area
Surface area of a sphere = 4*pi*radius squared
A surface area would be vital for determining volume
It would be the sum of the areas of each surface separately.
What is the surface area of this cone? Use π ≈ 3.14, and round your answer to the nearest hundredth. 8 in 4 in square inches
The surface area would be 1536in2

I would use 2*pi*r*(r + h) square units.

total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
Then the surface area of the solid would be measured in square feet
To calculate the psi needed to lift a weight, you would need to know the weight being lifted and the surface area over which the weight is distributed. You can then use the formula: psi = (weight / surface area). Make sure that the units of weight and surface area are consistent, such as pounds for weight and square inches for surface area.
No, they are two different things. Area encompasses the total object while Surface Area only encompasses what it implies. For instance, if you had a box, the Area would be the total size of the box, while Surface Area would only indicate the size of the top of the box. no. area is Lenth times width and surface area is what the area of the whole object.
The area of a beaker refers to the surface area that can hold a liquid, which would be the curved surface area of the beaker. This would require calculating the lateral surface area of the beaker based on its dimensions. The area cannot be determined with just the volume measurement.
